I am currently trying to make an application portable.
Where are the common places that an application puts its settings in a windows machine?
do you know know of any other places besides
-registry
-Currentuser/Application Data
-app folder
?
After you go over all the places you could think of, try running your app with Process Monitor in the background. Using the right filters, it will show you which registry keys and files have been accessed. And, it will show the exact stack trace of every operation, so you won't have a hard time finding the source of those calls.
